SUBNIARIN E BOATl Specification of Letters Patent.

Patented April 16, 1907.

Application filed April 23,1906. serai No. 313,266.

To alb whom t 'may concern:

Be it known that I, JOHN J. HAEPAIN, a citizen of the United States, ci the `\United States Navy, serving on board United States Steamship Marl) Zehead, have invented certain new and useful Improvements in Submarine Boats; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use Vthe same.

My present invention relates to improve- Y small boats of the t e adapted to carry torey pedoes attached to t e exterior vof the shell thereof, as' was 1described and claimed in my Patent No.'800,101,granted September 19,- 1905 ,but the said'boatmay be used for other purposes and as torpedo-boats, if desired. These boat`s, =fas.herein described, are not intended to cruise for any great lengths, but L are intended to be normally `carriedaboard,

,convenientway but preferably fis-described in my application,-Serial No. 313,267, filed* April 23, 1906, and entitled Im rovements boats. y Y

My invention will be understood by4 reference to the accompanyin drawings, in which Figure 1 is a side elevation of aboat constructed and equipped according to my invention. Fig. 2Ais a plan view of the boat shown in Fig. 1. Fig. '3 is a diagram illusf trating the operation of the steering-rudder. Figswl and 5 are diagrams showing in side elevation and/inpla'n the operation of the the connecti on of the detachable keel to the boat and illustrates the means for securing said keel in place ,and for releasing saine when desired. Fig'. 7 is a section on the line 7 7 ofFig.. 6 and-looking in the direction of the arrows. Fig;- 18 is a perspective view, on

gagingV t` sends of the keell members. Fig.

the'hatch-cover in the open position, and` Fig. 10is a planfview of the device shown in Fi 9.

- A representsthe body of the boat,-.whic is driven by; suitable mechanism, such as the er spacer for the rail C.

To each rudder a tiller d is connected, and

the rudders on each side have their tillers I' connected, respectively, tc two rods E on the inside .of the boat, which rods are rocked simultaneously by the arm F, fast to the band."1

G, which travels on the pulleys g and g and' is rotated by the hand-wheel Gr. The opera,- tion of these rudders D is illustrated in Fig.

-1,but1is,ful ly described and claimed in my lI-I are provided, fast on the rod c', which eX- `tends across the stern i the boat, 'as shown `secured,-w hich tillers -are oppositely disposed, as shown invFigs. land 4, and are connected, respectively, to the tiller-rods H2 H3, 'whichpass over suitable fair-leaders h2 and are connected to the arms I-I4 and H5, whichy carry, respectively, the treadles h4 and h5 and rock on the rod H". By pressing down one or the other of these treadles the balancerudders are caused to assume the position for diving or rising, as the case may be..

Suitable return-springs (not shown) may be provided for restoring the treadles to the initial position. Y

K re resents the-steering-rudder, which is journa ed in"su'itable bearings 7c and k. The rudder has a tiller K', which projects into the V-shaped casing C inthe stern of the boat. In this casin 'are mounted two pulleys k, (see Fig. 3,) w ch give a suitable direction to the tiller-rope K2, which is secured to the tiller K and passing over suitable fair-leaders czvis wound on the drum K3 of the steering-wheel K4. Thus it will be seen thatby turning the wheel K4 the boat maybe steered to the rightl or left as desired, while by pressing on one or the other of the treadles Il* or h5 the longitudinal lOO diving, and, finally,` the diving-rudders D .may be caused to wedge the boat down or up by turning the wheel G. v

The rising or diving' of the boat may be 5 facilitated by using a detachable keel, such as is shown in Figs. 6 to 8. In thesej figures, A represents the keelson of the b oat, which is preferably located beneath suitable bal,-

last-tanks A2, which ballast-tanks may bef ,filled or emptied in any of the well-known ways for accomplishing this resultf In th keelson A, I provide notches a to engage the y rounded lugs m of the keel members M', two of which together constitute a vdetachable keel M. The other ends of these keel niembers M carry lugs m above the shoulders fm2.V These lugs engage iii-recesses n in the locking-block N, (see Fig. 8,) and this block'has a squared nut N on its upper side, screw- .threaded, as at n', to receive the screw p on the end of the rod I), which passes 'through the stuffing-box a2 and is held beneath .e same by a set-collar p0, and is provided with a hand-lever P and 'a handle p. T he nutI N is made angular and projects up into an angular recess in the boss a on the keelson A. In order to attach the keel to the boat, the keel members M have their lugs m inserted in the notches aand the lugs m inserted in the recesses n in the block N, the parts beingrtlien in the position indicated in dotted lines in Fig, 6. Now by shoving up on both of 'the keel members until the nut N engages the screw-threads p and 4then screwing up ou the screw-rod P' the keel 'members may be brought to the locked position, as shown in full lines in Fig. 6. To release the keel members, turn the handcrank P through a sufficient -number ofrev'- olutions to release the block N and the keel members will fall down, iirst to the position shown in dottedliues in Fig. A6, and then these members,l with the block NlQ-will become entirely released and: 'will' `fall bodily away from the boat. This dropping of the Y keel Will increase the reserve buoyancy. of the boat sufficiently to cause the boat to rise should the diving apparatus fail to operate r should the density of the system 'prove too great, as from springing a leak or from any other cause.y y

Q represents the hatch, which has a'tapered `coaming, as shown, and is provided withside bu'lls-eyesg, preferably elongated, and with fore-and-aft-bulls-eyes g, as shown in Fig. 9. The hatch-coaming s'secured to the hull ol" the boat by means of a .flange 'g2- The top. oi "fthe `hatch Vis closed -by two members R', liingedfat o posi-te ends of the hatch, as at r, provi ed .with-'suitable bulls-eyes r. rese members R are providedwith flanges 'er Liwliich drop down and make'water-tight connections with the flanges s 'ofthe hatch. yAlong 'the` edges of'the inside o t'he hatch and' 6 5 secured to the interior of the members R are rubber or canvas curtains Rf, wld-:li form splash-boards or curtains when the members R of the. hatch-hood are in the miser! position, as shown in Fig. 9. Then llwsi members are lowered, these curtains drop down to the interior of the hatch.

In the drawings I have omitted for the sake of clearness apparatus for attaching the torpedoes to the exterior ofthe boat, as these are fully shown and described in my patent 3. aforesaid and as they do not constitute a part of my present invention. l

It will be obvious that various modifications might be made in the herein-described apparatus which could` be used without departing from the spirit of my invention.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is v l. An immersion. 'ap aratusfor submarine boats comprising a rai secured to each side of the boat and spaced therefrom, diving rudders journaled between said railand the boat-body', means' located in the interior of the boat for simultaneously operating all of these rudders, 'balancing rudders pivoted near the stern of. the boat and adapted `rto tilt the longitudinal axis of the boat, means operable from tlie'interior of the boat for rocking said balancing-rudders in either di rect-ion, .and a detachable keel, comprising two members connected to the hull-body, a y

sired, andmeans for drawing'said'block into position for locking said keel in place and for releasing said block when desired, substantially as described.

3. In a submarine boat, a detachable keel comprising two members pivotally connected at their outer ends to the bottom of the boat and provided Withlugs on their-inner ends,r in combination with a recessed block adapted to engage said lugs and to release same when desired, a nut secured to or integral with said block, and a rod provided with screw-threads adapted to engage said nut'and `projecting into the interior of the boatfwith means for turning said rod and causing it to 'engage or to release said block, substantially as described.

4. In a submarine boat, the combination with a keelson provided with a recess adapted -to receive a detachable keel, with notches at each end 'of said recess, two keel members having lugs on their outer ends adapted to engage said notches, and also being provided IOO i with lugs on their inner ends, a recessed block l' adapted to engage' said lugs'on the inner end, ani means operable from the interior of the `boat for drawing up said recessed block to 5 lock saidkeel members into position or for releasing said recessed block and the keel members and allowing them to fall awayv from the boat, substantially as described.

5. In a submarine boat, the combination io with a keelson provided with a recess adapted to receive a detachable keel7 with notches at "each end of said recess, .two keel members having lugs on their outer ends adapted to engage said notches, and also being provided Q 15 with lugs on their inner ends, a recessed block adapted to engage said lugs on the inner end,' a nut secured to or integral with said block, and a rod provided with screwthreads and rejecting into the interior ofthe boat and4 ad? means for rotating said rod, to cause said screw-threads to engage or to release said nut,

substantially as and for the purposesdescribed.

In testimony whereof I affix my signature z 5 in presence of two witnesses.
